To-aZZ whom it may concern; p Be it known that I, l VI LIAM C. BAXrnn, a

citizen of the United; States, residing at Beverly, in the county ofEssex and State of Hassachusetts, haveinvented certainlimprovements inDeliverylvlechanisms, of.

which the following description, in connect1on w th the accompanyingdrawings, is a specification, l1ke reference characters on the drawingsindicating like parts in the several" figures. This lnventlon relatestomachmes ior operating upon blanks.- The invention is hereblanks afterthey are 'formed or operated. upon. The illustrated machine isespecially designed to die out heel lifts for boots: and

shoes and to'deliverthe blanks in stacked; The invention, however," isnot ilto application to thistype' of machine or to use for this purposeY Machines for forming blanks as by dieing] out heel lift blanks fromsheet material com monly are constructed to 'discharge the blanks in apromiscuous, heap. It is then" necessaryto sort the blanks, eitherarranging the blanks in stacks or placing them inproper' relativepositions in magazines, atthe same time rejecting unusable and imperfeetblanks and pieces of scrap. The sorting and stacking or. magazining ofblanks is thus rendered excessively expensive. It'has been proposedtoprovide a'discharge or deliverymechanijsm extending out in front of sucha machine substantially. in line with the work supporting and blankfeeding inecha nism of the machine. Such a:construction is open toseveral objections, one of the-most important beingwthat it-requires'adisadvantageous or floorspace; 1 I a I a It is an object of the presentinventionto rovide' a compact machine organization adapted for dieingout orotherwi'se forming or operating upon blanks, which will be so 5constructed and-arranged as to deliver the" blanks position for. readyremoval in stacks and which, at'the same time, will be: comparativelysimple: and constructed so to deliver the blanks that-they may bereadily inspected before they are removedirom the 1 a a; tions-8transversely: alined and through machine.

It is frequently desired for the purpose of increasing the capacity-ofthe machine to die out or otherwise operate upon a plurality of; blanks:simultaneously as by a double or-muh tiple die. It is a, further objectof the invention to provide delivery mechanism adapted" to, be employed:in connection with v mechanism for-dieingout or forming a plurality ofblanks simultaneously which Willbe' con-I structed-to take theblanksirfrom the dieing out or forming mechanismand deliver them 1 atastation convenientfor removal in stacks asiby delivery toia horizontaltable in par-.-

The upper ends of the sideplates are secured to the under surface of a block 10 which supports, inthe illustrative construction, a double die 12, which'is the cuttingmember of a heel lift cutting machine of well-known construction.Spacing the side plates 4 and serving as a partition to divide thedelivery chute into two passageways is a member 14 the upper end ofwhich is in alinement with and closely adjacent to the cross cuttingbar-16 of the die 12. The other end of the member 14 extends to thepoint 18 where it is secured, said member thus forming the floor of onepassageway and the upper side of the other passageway. The fourth wallof each passageway in the chute is made movable and is shown to consistof a strip 20 or a strip 22-of sheet metal or other suitable material towhich is secured pinsor bolts-extending through slots 24 in the plates 4and carrying wing nuts 26 by which the pins 01' bolts may be secured inadjusted position in the slots 24. By the means described, the strips20, 22 may be accurately alined with the end.

portions of the cutter member or die 12 and hence as the blanks passfrom the die they will be received into the passageways on each side ofthe partition 14 and conducted to and alongthe independent chutes 28, 30which are laterally offset from each other in order that the blanks mayeventually be delivered in rows in side-by-side' relationship on a tableor other support. While the chutesare shown combined in one structureadjacent the plate 10, it is clear that they may be constructedpractically independent throughout. In addition to the supports alreadydescribed .for the wall 20, there is 7 provided a bolt 32 passingthrough a slot 33 in the flange in one of the side members 4' andattached at its lower end to the strip 20 and to a continuation of saidstrip in the form of a strip 34 (Fig. 2) which is also supported by wingprojections 36 slotted to receive bolts which secure them to angle irons38 on the inturned flange of the chute. Since the wing projections 36and the angle irons 88 have slots extending substantially at rightangles to each other, the strips 34 may be readily adjusted to the sizeof the blanks passing through the chute, adjustment of the strip in themanner described requiring movement of the strip longitudi nally of thechute as well as toward and away from the upper flanges .40'of thechute.

As may be inferred, the chute 30, is provided with a similar strip 34 orupper wall for the passageway adjustably secured in place by meansidentical with that described iniconnection with chute 28.

In the construction shown, the side plates 4 of the first portion of thedelivering mechanism-are split at the point 18 to 01111 the while atintermediate points the chutes are secured by braces .44 to a member 46which constitutes part of the supportingv structure for the deliveringmechanism. Since the sides of the delivery chutes are secured to theplate 10 and to the supporting member 46 and to the table 42'by meanswhich hold them firmly in position, the bolts, which may be arranged topass through the flanges 8, may be supplied at only necessary points. Asa means of strengthening the chutes 28 and 30 and holding them in thedesired relative position, they are interconnected by means of a curvedplate 48 secured to brackets 50 attached to the sides of the chutes.

As will be seen from an inspection of Fig. 2, of the drawings, thechutes 28 and 30 end in portions which are arranged in parallelism andpractically in the same horizontal plane in order that the streams ofblanks coming from the chutes may be located in a positionreadilyaccessible to the attendant who is to remove the blanks "for the purposeof stacking them for packing, or for other purposes, as, for instance,in magazines for 1186111 other machines. In

the construction shown, the chutes end at the edge of the table 42,though obviously the sides of the chutes may be extended across thetable in the form of open troughshaped members 52 which receive theblanks as they issue from the chutes. Preferably these trough-shapedmembers 52 are made.

of pieces of wood of considerable thickness so as not to present anysharp edges to :the hands of the attendant. It will be evident that thestream of blanks when thusfexposed may be readily inspected by theattendant to the end that'imperfect blanks orscraps of material may berejected and perfect blanks be readily removed in the stacked relationin which they appear wherein all of the blanks are .positioned withtheir analogous edges facing all in the same direction, thus making itunnecessary to performany asserting operation. As will be observed froman inspection of Fig. 2,

the blanks in the chute 28 have their con-' vexly curved edges allfacing upwardly,

while in the chute 30 the straight edges pf the blanks face upwardly.

llln the blank forming machine of which the double die 12 is anessential element,

the strips of material from which the blanks are formed are fed acrossthe face of the a die in either direction at right angles to the longaxis of the die. Inasmuch as the feeding mechanism which is ordinarilyless floor space in one direction and stillpresent the delivery table inthe best light at the window. Hence the delivering mechanism is soconstructed that at its blank receiving endone chute or blank carryingpassageway lies above another chute or passageway and if this relativeposition of the chutes continued throughout the blanks would normally bedelivered in streams one above another in a manner which would make itdiiiicult'or impracticable to handle the blanks properly. In order todeliver the streams of blanks in side-by side relationship, the chutesare laterally ofi's'e't at an angle to each other throughout a portionof their lengths and finally'are brought into practically parallelrelationship with the delivery ends in substantially the same horizontalplane, thus adding greatly 'to the ease with which the attendant mayinspect the blanks and remove the same, as described. In theillustrative construction, the parallel portions of the chutes are invertical planes which are parallel to the vertical plane of the combinedchutes at their blank receiving ends.

In the operation of cutting machines of the kind in which a die is thecutting element, the blanks are formed intermittently and forcedstep-by-step along the chute, the freshly cut blanks forcing those whichpreceded them along the chutes until they appear at the delivery end ofthe mechanism. Because of the efficient arrangement disclosed, it hasbeen found that the attendant may readily take care of the product ofthe commercial heel lift cutting machine, for instance, which has acapacity in theneighborhood of 500 liftsper minute. Previously itrequired constant work on the part of several individuals to sort theperfect lifts from an occasional imperfect lift or piece of scrap andposition the lifts with their analogous edges pointing all in the samedirection for stacking, for packing purposes, and for introduction intomagazines. 1

Having thus described my invention, what I claim as new and desire tosecure by Let-- ters Patent of the United States is 1; In a device ofthe class described, clelivery chutes having blank receiving portionsarranged side by side in one plane for receiving blanks from a pluralityof'sou-rces of supply and having relatlvely oifsetportions ending inportions parallel to each other and with said plane and so arranged thatthe space above each end portion is unobstructed, for delivering theblanks to a table or other support in positions readily accessible tothe workman.
